The Freedom Fill Auxiliary System
The Freedom Fill Auxiliary System is a complete installation kit for your new ATTA aluminum auxiliary diesel tank. This fuel system is designed for full size Ford, Dodge, and GM/Chevrolet diesel trucks.
The Freedom Fill Auxiliary System meets or exceeds all DOT, EPA, and VESC-22 regulations.
How it works:
ATTA’s Freedom Fill Auxiliary System is a computer controlled fuel system. The small computer module mounted under the dash, sense the level of the factory tank and the auxiliary tank. When the factory tank reaches approximately a half a tank, the computer box will turn on the auxiliary in-line fuel pump. This will then begin to transfer fuel from the auxiliary tank to the factory tank. When the factory tank reaches approximately three-quarters of a tank, the auxiliary in-line fuel pump will shut off. Whenever the auxiliary tank is transferring fuel, a small light on the switch will turn on indicating fuel is being transferred from the auxiliary tank to the factory tank. When the auxiliary tank is near empty, the in-line fuel pump will not turn on. The aluminum auxiliary tank will have its own 2” gauge so you know how much fuel is remaining in the auxiliary tank. If the factory fuel tank drops below a half a tank, then you know the auxiliary tank is empty. The Freedom Fill Auxiliary System has an on/off switch which allows you to deactivate power to the system.
The Freedom Fill Auxiliary System is designed to work with Ford, Dodge, or GM/Chevrolet full size diesel trucks. This is one of the easiest systems on the market to install to you truck. Anyone with basic mechanical skills can install this system themselves in a matter of 5 to 6 hours or better. ATTA, inc. does have an extensive installing dealer network, please contact us for a dealer near you.
The Freedom Fill Computer Box will be programed to match your specfic truck. During checkout, you will be asked to identify your make and model.

11. (B) Locate the factory fill neck on the inboard side of the truck bed. The vent line adapter has both a 5/8” & ¾” step, the same vent line adapter will be used for both sizes. (If it is a 5/8” vent line, place it upon the 5/8” portion (lower step) of the Vent-Line Adapter. If it is a 3/4" vent line, place it upon the 3/4" portion (upper step) of the Vent-Line Adapter.) Mark the factory vent line where the cut should be made, insuring that you will have enough factory vent hose to slide over the adapter. Cut a small section (approx. 1” or more) out of either the 5/8” or 3/4” factory vent line. Place a large hose clamp on each side of the cut section. Insert the vent-line adapter and tighten the #12/#10 hose clamps. NOTE: On some trucks with metal fill vent lines, it will be necessary to cut a portion of the metal tube and add the applicable rubber hose to install the Vent Line Adapter. Do not “kink” the vent hose. It does not matter whether the 3/8” fitting or the 5/16” fitting face the factory tank.
*Note: Vent Line Adaptor may differ than picture shown.
((Installer Tip: When cutting a metal fill vent line, place a magnet on the line to catch any metal shavings.))
**Warning: When mounting the Vent Line Adaptor, be sure that the position of the factory fill vent line, does not allow the line to retain fuel. For example, a low portion of the hose that will hold fuel and not allow air to escape when normally filling the factory tank. This will cause spit-backs for the station fuel nozzle. Any fuel in the line needs to drain to the factory tank.

How the System Works
When the system is turned on, the Freedom Fill Controller box will sense when the factory tank is approximately at a half a tank, the controller box will then turn the auxiliary in-line pump on, filling the factory tank to approximately three-quarters of a tank. The light on the switch will turn on allowing you to know when the system is transferring fuel. When the factory tank reaches approximately three-quarters of a tank, the pump will then turn off. When the auxiliary tank is empty, the system will not turn on. If the factory tank goes below approximate one-half of a tank, you know the auxiliary tank is empty. When the switch is in the off position, the auxiliary gauge and computer will be off, and will not transfer fuel from the auxiliary tank to the factory tank.
When the truck or the system first turns on, the pump &light will turn on for approx 5 seconds, then turn off. If the factory tank needs fuel it will then turn back on and begin to transfer fuel. If the factory tank is above approx ½ a tank, the system will remain off until the factory tank reaches the appropriate level of approx ½ a tank. If the truck or Freedom Fill System is shut off during fuel transfer, it will not turn back on until the factory tank reaches approx half a tank.
